Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a detachable air duct for a vacuum cleaner. Background Technique

[0002] A vacuum cleaner, also known as an electric vacuum cleaner, is a household appliance that has a history of 100 years and has become an indispensable device in many families. Its working principle is based on Bernoulli's principle. That is, when the fan blades on the motor rotate, they will push the air forward, causing the particle density in front of the fan to increase, thus forming a pressure higher than the external environment. At the same time, the particle density behind the fan decreases, forming a pressure lower than the external environment. This pressure difference causes suction to be generated inside the vacuum cleaner, forming a partial vacuum. This suction can suck up dust and debris on the ground, filter and collect them through a dust collection bag or filter screen, and the purified air is then released back into the room, playing the role of cooling the motor and purifying the air.

[0003] A vacuum cleaner connecting pipe structure and a vacuum cleaner with the authorized announcement number of CN 216823224 U in China. The middle connecting pipe and the upper connecting pipe of the vacuum cleaner connecting pipe structure are hinged through a hinge seat, and relative rotation can be realized, so that the vacuum cleaner connecting pipe structure can be bent. When cleaning narrow spaces such as under the bed or under the table, by loosening the first buckle, the upper connecting pipe can be flipped around the hinge seat and form a suitable angle with the middle connecting pipe. Users do not need to bend down or squat to clean, which greatly improves the convenience of use, and the assembly is simple and practical.

[0004] However, there are still some deficiencies in the use of this patent. The structure between the body of the existing vacuum cleaner and the air duct is fixed and non-detachable. When the air duct is blocked, it is not convenient to maintain and repair the air duct. In addition, the sealing performance at the connection between the air duct and the body of the vacuum cleaner is poor. When the air duct is impacted by wind for a long time, cracks are likely to appear, resulting in a significant reduction in the sealing effect. Content of the Utility Model

The rotating gear 302 is rotatably connected to the vacuum cleaner body 101. The rotating gear 302 is meshed with the second rack part 305. On the side of the plug-in block 303, there is a first rack part 304. The side of the first rack part 304 is meshed with the rotating gear 302. Inside the telescopic groove 105, there is a spring 306. One end of the spring 306 is elastically connected to the bottom of the plug-in block 303, and the other end of the spring 306 is elastically connected to the inner wall of the telescopic groove 105. Inside the spring 306, there is a damping rod 307.

[0030] Among them, by setting the vacuum cleaner assembly 1 and the installation assembly 3, the fixation of the air duct is realized, so that the air duct and the vacuum cleaner body are detachable structures, which can quickly install the air duct and also facilitate the maintenance and replacement of the air duct. When installation is required, first press the moving block 301 respectively. During the process that the moving block 301 moves along the moving groove 106, it drives the rotating gear 302 to rotate. When the rotating gear 302 rotates, it drives the plug-in block 303 to move, and at the same time the spring 306 is compressed.
